FRDM-KL25Z and P5V_USB

I have been working with the Freedom board for some time now. Recently I was asked to develop a demo using this board.

 

My demo is making use of a couple of Arduino shield and in order for viewers to better see what exactly is being used I have had a larger breakout board built, whereby I can unstack the boards and lay them all out, side-by-side. I am powering up the Freedom board via J9-20 (5V-9VIN). One of my shields is expecting 5V on J9-10 (5V_USB). Looking at the available documentation it is apparent that J9-10 gets voltage off of either the USB_SDA or USB_KL25Z connectors.

 

Here is my question, provided my shield can accomodate 5-9V, which it can, are there any issues with my simply tying J9-10 to J9-20? From what I see J9-10 does not seem to be connected to much of anything on the Freedom board, aside from the Shottky diodes, off P5V_SDA and P5V_KL25Z.

 

Thanks,

Cameron
